Tifosi's Veloce Fototec glasses are stylish, lightweight specs boasting Tifosi's exceptionally tough Grilamid frames and their Fototec lenses that automatically adjust to changing lighting conditions so you can always see clearly. Their open-frame design and large, impact-resistant, polycarbonate lenses offer a wide field of vision and protect you from debris, while the lens vents ensure fog-free vision. And, you'll love the hydrophilic rubber temples and nose pads that adjust in all directions and grip better when wet for a comfortable fit that stays put.

Tifosi's Fototec lenses use variable tint technology to rapidly adjust to changing light conditions for superior clarity and protection. In bright sun, photochromic particles embedded in the lens react to UV rays, darkening the optics so you'll never squint. With cloud cover, the particles return to their previous state to let in more light.

I use these shades while mountain biking. They are very clear, and are perfect for cloudy conditions. Although they are not supposed to fog up, they tend to do it while I'm taking a break and standing. Gets annoying. However, as soon as I start riding again, they clear up. They are very comfortable to wear, even after hours of riding. I would recommend them to anyone wanting a nice pair of transitions shades to ride in.
